jiofi router is a portable wifi hotspot dongle it provides data
connectivity to multiple users upto 10 devices and one on usb.
by using jio4gvoice app enables the devices. to configure jiofi
router by logon into 192.168.1.1 or jiofi.local.html
those url's are useful to setup your jiofi device like username & password change, storage
slot access, battery status, changing broadcasting ssid etc. also, it provides
an excellent battery backup, up to six hours.

Battery Bank Basics

Off Grid Battery Bank

Building a battery bank and having a method of keeping them
charged is one of the first steps in building an alternate energy
system for off grid applications. A battery bank can be used to run lighting, t.v.,
radio, microwave, etc.

Sizes range from a few batteries, a charging system and an
inverter, to hospitals and universities that need power for
lighting and important equipment.

All battery systems have to be properly recharged. This is
done by the generator or other source of alternate energy. The
larger the system, the larger the generator or other source of
charge has to be.

Batteries are rated in voltage and ampere hour capacity. The
greater the amp hour capacity of the battery bank, the longer it
can power equipment before needing to be recharged. Energy from
the generator or alternative energy source can be stored for later
use.

With the cost of fuel, oil and maintenance it makes sense.
Rather than running a generator all the time to get power, it
only has to be operated when equalization charging takes place
and when the system does not have sufficient capacity to power
heavy loads.

The initial investment in a battery bank is well worth it,
providing power 100 percent of the time. Battery backup is increasingly used in grid tied systems as well.

Battery banks are wired and sized to produce energy needed in
voltages ranging from 12, 24, 48, 60,vdc and sometimes higher.
The higher the loads (demand) placed on the system, the higher
the voltage has to be to match the input voltage required by more
powerful inverters that are needed for larger loads.

Once you have figured out your daily watt hour consumption and
have revised that figure by practicing energy management, you can
calculate your battery capacity.

Energy is ability to do work. 1 newton of force over
1 meter is 1 newton-meter or joule or watt second
of work done.

Power is the rate of doing work. lifting 1 pound
weight
1 foot in one second is 1 foot-pound per second. if
you
lift 550 pounds one foot in one second that's 1
horsepower
of power required.

Most people would have problem lifting 550 pounds
(249.48 kg),
directly. but you can lift that weight with a winch
over
longer time and the same amount of work was done, just
took
longer so required less power.
same principle with levers or pulleys. the force is
reduced
but distance the force is applied increases. so total
of
force * distance remains the same. (minus any friction
loss)
the same amount of work can be done by letting the
weight
fall, but then you have to do work to lift it back up.

1 btu = 252 calories

1 btu = 1055 joules (watt seconds) = .293 watt hours

1 btu raises 1 pound of water 1 degree fahrenheit

1 calorie raises a gram of water 1 degree celsius
1kilocalorie is used for diets = 1 kilogram water 1
deg celsius

energy is a scalar, with basic si units of
kg-m^2/sec^2
(also defined to be the joule).

kinetic energy of a moving mass is 1/2 * m * v^2
joules, m is mass in kg and v is velocity in
meters/sec.

momentum is a *vector*, with basic si units of
kg-m/sec.

rotational momentum is p = j x w, where j is the
moment of inertia (same as used for calculating
rotational
kinetic energy).

ke of rotationally moving objects
equation ke = 0.5 x j x w^2, where j = moment of
inertia (rotational analog of mass, related to the
object's mass and its distribution around the axis of
rotation), an w = rotational speed, radians/second.
acceleration is the change in velocity/time
earth gravity acceleration is about 32 feet/sec^2
or 9.81 meters/sec^2. that means that velocity
of something falling without wind resistance or other
force, will increase 32 feet per second, every second
or 9.81 meters/second, every second. stopping or
deceleration is calculated the same.

v is velocity, d/t, meters/second or feet/second
d is distance
a is acceleration, change in velocity/time, m/s^2
t is time in seconds
